Proportion free of gastric cancer in patients with gastric or gastroduodenal ulcer (A) and duodenal ulcer (B) in the eradication group was compared according to results of eradication therapy, using Kaplan-Meier analysis. A: The incidence of gastric cancer was 29/1572 (1.85%) in patients with successful eradication and 8/413 (1.94%) in patients with failure of eradication (log-rank test, P = 0.92); B: The incidence of gastric cancer was 2/845 (0.24%) in patients with successful eradication and 3/216 (1.39%) in patients with failure of eradication (log-rank test, P = 0.03).
